According to a Finnish website, you can download AirBuccaneers for free from steam on 6.12.2012 in celebration of Finland's independence day. (The link is all finnish gibberish, so open it only if you dare)
AirBuccaneers is officially released on 5.12 and I included the word "maybe" in the thread title because I don't know if this offer is available outside of Finland because the source material doesn't really explain a lot.
If the game isn't free for you lot, then I apologize for making this thread. We'll see.
